3. INSTALLATION OF THE DEVICE
3.1.- PRELIMINARY RECOMMENDATIONS
In order to use the device safely, personnel operating it must follow the safety meas-
ures that comply with the standards of the country where it is to be installed; operators
must wear the required personal protective equipment (rubber gloves, approved facial
protection and flame-resistant clothing) to prevent injuries from electric shock or arcs
caused by exposure to current-carrying conductors, and they must heed the various
warnings indicated in this instruction manual.
The CBS-2000AB/CBS-1600A device must be installed by authorised and qualified staff.
The power supply plug must be disconnected and measurement systems switched off before handling,
altering the connections or replacing the device. It is dangerous to handle the device while it is pow-
ered.
Cables must always be kept in perfect condition to avoid accidents or injury to personnel or installa-
tions.
Restrict the operation of the device to the specified measurement category, voltage or current values.
The manufacturer of the device is not responsible for any damage resulting from failure by the user
or installer to heed the warnings and/or recommendations set out in this manual, nor for damage
resulting from the use of non-original products or accessories or those made by other manufacturers.
Do not use the device to take any measurements if an anomaly or malfunction is detected.
Check the surrounding environment before starting to take measurements. Do not take any measure-
ments in hazardous or explosive environments.
Before carrying out maintenance, repair or handling of any of the device's connections,
the device must be disconnected from all power sources, both from the device's own
power supply and the measurement's.
Contact the after-sales service if you detect that the device is not working properly.

Instruction Manual
3.2.- INSTALLATION
When the device is on, its terminals, opening covers or removing elements may ex-
pose the user to parts that are hazardous to touch. Do not use the device until it is
fully installed.
The device must be installed inside a medium or low voltage electric panel or enclosure, with DIN rail
mounting (IEC 60715).
The device has a LED (CPU) that indicates voltage presence. Even in the case that the
aforesaid LED is off, the user still needs to check the device is disconnected from any
power supply.
The device must be connected to a power circuit protected by a fuse according to its power and con-
sumption rating. It must be fitted with a circuit breaker or equivalent device to disconnect the device
from the power supply.

3.4.- WGB AND WGC TRANSFORMERS
When the device is on, its terminals, opening covers or removing elements may ex-
pose the user to parts that are hazardous to touch. Do not use the device until it is
fully installed.
The transformer is designed for wall-mounting or DIN-rail assembly with an accessory for installation.
The WGB /WGC is a feed-thru busbar type transformer, where the conductor cables to be measured
must pass through the inner hole or window of the transformer.
3.4.1. PANEL INSTALLATION
For panel installation, 4 clamping clips, are provided with the transformer, see Figure 3.
Figure 3: Clamping clip.
The clamping clips which must be installed on the WGB/WGC as shown in Figure 4.

3.6.- INSTALLATION CONNECTIONS
3.6.1. CBS-1600A
All active conductors that supply the loads or part of the installation where protection is required must
pass through the associated WGC transformers (2-wire connection).
3.6.2. CBS-2000AB
All active conductors that supply the loads or part of the installation where protection is required must
pass through the associated WGC (2-wire connection) or WGB (connection via RJ-45 cable) transform-
ers.
For each of the type-B channels to be monitored, connect the WGB transformer to the CBS-2000AB or
to the next transformer in the installation using the RJ-45 cable, Figure 14.

Figure 14: CBS-2000AB - WGB connection.
Note: If a RJ45 connection cable other than the one supplied with the WGB is used, it must have a
cross-section of 4 x 2 x AWG24/7. The maximum distance from the CBS-2000AB to the furthest WGB
must be of 9 metres.
The CBS-2000AB detects the transformers automatically, assigning each of them a specific channel.
If the automatic channel connection carried out by the device does not match the installation carried
out in the output relays, the numbering of the channels in the CBS-2000AB can be changed without
modifying the installation (see "6.5 .- CHANNELS").
If the installation is modified and it involves new transformer, a replacement of the WGB ... the CBS-
2000AB will detect this change and light the screens in yellow, see “5.1.- PROBLEMS OR CHANGES IN THE
INSTALLATION (Model CBS-2000AB)”.
